FRANKLIN G. HOBART, or BELOIT, WISCONSIN, ASSIGNQR fro FAIRBANKS, MORSE & COMPANY, or onro eo, ILLINOIS, A CQRlOItATION OF ILLI- NOIS.

Be it known that I, FRANKLIN G. HoBAR'r,

, a citizen of the United States of America, re-

nular rim or flanIge siding at Beloit, in the county of Rock and State of.Wisconsin, ,have invented certain new and useful Improvements in Sprayers, of which the following is a. specification, reference being had therein to the accompany-' in drawings. i

y invention relates to new and useful imrovements in spraye'rs, or spray nozzles, and 1s articularly ada ted for use in scrubbers for suction gas ro ucers. Q i The object o the invention isto" produce a sprayer which may be adjusted to give an evenly scattered spray whi e varying the'volume of water.

The novel construction and arrangement of parts by which I have accomplished this object will be more fully hereinafter described and set forth in the claims. In the drawings, Figure 1 is a vertical central section through the sprayer, and Fig. 2 is a perspective view of the adjustable closure.

A is a preferably tubular body member having one end open and at the other an ana seating around the edge in the top of the scrubber of the opening B and A is a preferablconical nozzle project-" ing into the opening and ham an axial outlet opening a. The interior 0 the body member forms a cylindrical chamber having a downwardly and inwardly tapering lower end terminating in the outlet a. The inlet C to the casing 1s tan ential and is arranged with a suitable glan C for connection with the water sup ly. D is a combined closure for the open end of the body and valve for the inlet. and consists in a circular top D and an annular projection E fittin the chamber in the body member. The ower edgeof this projection forms a s iral d and the ends of the spiral are connecte by a vertical ortion e.

When a full volume 0 water is desired, the

closure D is rotated to bring the portion 0 beside the inlet 0, and when a lesser volume is desired the closure is rotated tobrin the portion e partially across theinlet. 1 hus the volume of water is restricted without re.- stricting the pressure.

1 To facilitate the adjustment of the valve;
